BED FOR INVALIDS.

Specification of Letters ratent.

- Patented Oct. 4, 1910.

' Application filed February 24, 1910. Serial No. 545,672.

To all whom it may concern:

Be it known that I, ARTHUR FREMONT CRANDALL, a citizen of the United States, and a resident of Beresford, in the county of Union and State of South Dakota, have invented a new and Improved Bed for Invalids, of which the following is a full, clear, and exact description.

My invention relates to beds, and it has for its'objectto provide a plug adapted to close a commode opening in the mattress of the bed, the member carrying the plug being adapted to be connected to a section of the mattress support, so that the plug will be moved relatively to the commode opening when the said mattress section is raised or lowered.

Another object of the invention is to pro videmeans by which a section of the mattress support may be raised and lowered.

Still further objects of the invention will appear in the following complete description of the invention.

In this specification I will describe the preferred form of, the invention, it being understood that the scope of the inventionis defined in the appended claims.

In the drawings like characters of reference indicate corresponding parts in all the figures, in which Figure 1 is a longitudinal section of the bed; Fig. 2 is a plan view of the bed shown in Fig. 1, the corner posts being in section and a portion of the mattress being broken away; Fig. 3 is a sectional view on the line 3-3 of Fig. 1, and Fig. 4 is an enlar ed detail sectional view showing the mem r carrying the plug about to be locked in horizontal position.

By referring to. the drawings it will be seen that the bed is provided with corner posts 5, which have lugs 6 which engage in grooves 7 in the side bars 8, the side walls of the grooves 7 converging downwardly to prevent the lugs from slipping therethrough. The corner posts 5 are connected by end bars 9, there being two end bars 9 dlsposed at the head of the bed and the same number at the foot, the end bars being disposed one over the other, respectively.

Secured to the lower .end bar 9, at the head of the bed, and projecting toward the foot, is a bar 10, secured to a mattress sup port 11, which is rovided withhooks 12 disposed over the ower end bar 9 at the foot of thebed, and hooks 13, one at each side, disposed on the side bars respectively. The bar 10 and the mattress support 11 form part of the frame. Disposed on the mattress support 11 there is a mattress 14, having a commode opening 15. The mattress has a transverse cut '16 along its under side a short distance from the commode openingand in the direction of the head of the bed, to permit the portion 14 of the mattress, which is disposed near the head of the bed, to be raised relatively to the remainder of the mattress. This portion 14: of the mattress is disposed on a mattress support 17, which is pivoted to a transverse bar 18 secured to the side bars 8. A lever 19, having bifurcated arms 20, is fulcrumed at 21 to the bar 10, the bifurcated arms 20 being disposed one at each side of the bar 10. To an arm of the lever 19, a late 22 is hinged, a plug 23 being mounte on the plate 22 by means of springs 24, the plug being adapted to close the commode opening 15 in the mattress. I prefer to cover the walls of the commode opening and of the plug with oil cloth, or other similar material which may be readily cleaned. In order to obtain a rigid connection between the plate 22 and the lever 19, when desired, guideways 25 are secured to the plate 22 and to the lever 19 respectively, a bolt 26 being' provided which works in the guideways 25 and may be used to connect rigidly the plate and the lever.

In an elongated slot 26 in the bar 10, is

pivoted a lever 27, the arms of which are.

bent relativel to each other, the upper arm of the lever 2 carrying a roller 28, which is adapted to travel in a guideway 29 in the mattress support 17. To the other arm of the lever is secured a cord 30, which iscarried over a pulley 31, the cord being then secured to a shaft 32 disposed in a vertical tube 33 at the head of the bed, the tube 33 connecting the upper and lower end bars 9 and being provided with suit-able bearmgs in which-the shaft 32 is journaled. To the top of the shaft 32 is secured a crank 34 and a ratchet wheel 35, a pawl (not shown) being mounted on the upper end bar 9, to enga e the ratchet wheel 35.

ivoted on one of the bifurcated arms 20 of the lever 19 is a locking member 36, this lockin member 36 having two arms 37 disposed in the same direction, the upper arm the lower members 5 pro3ecting into the guideway ,arm 40 being disposed preferably at right angles to the arms 37 and being adapted to be dis osedunder the bar 10 to lock thereto the bi urcated arms 20 of the lever 19.

The corner posts 5 are constructed in two sections, which are telescopic respectively,

upper members 5 which are tubular. These members 5 and 5' may be held relatively to each other by any suitable means, but I prefer to construct the lowrr members 5 with orifices in which are disposed pins 41, on which the upper members 5* rest.- In the upper members 5 are disposed springs 5 which'press against the u per terminals of the lower members 5 ans hold the lower members yieldingly extended when the pins 41 are withdrawn;

To one of the corner posts 5 is pivoted an arm 42 having a ring-like termmal 43 in which is disposed a commode 44, the rim 45 of the'commode resting on the ring-like terminal 43. V

' It will be understood that the bed ma be inclined downwardly toward the hea or foot by adjusting the upper members 5 of the corner posts relatively to the lower memhers-5", the bar 9, the mattress support 11 and the sidebars 8 being mounted on the upper members 5". Irrespective of the position in which the body of the bed may be disposed relative to the corner posts and irrespective of the position of the mattress section 14, the plug 23 may be lowered, to permit the commode to be disposed under the commode opening 15. If the condition of the invalid is such as not to permit the nurse to lift the mattress section 14, the plug is lowered by withdrawing the bolt 26 sothat the plate 22 will fall carrying the plug, but in most cases the invalid is able to sit up in bed and when such is the case,

the nurse may, by turning the locking member 36, disengage the arm 40 from the underside of the bar 10, which action will cause the upper arm 37 carrying the flange 38, to turn over the guidewa 29. When this has been done, the nurse, y turning the crank 34, will raise the mattress support 17 which is pivoted to the transverse bar 18, carrying with it the bifurcated arms 20 of the lever 19, and as the plate 22 is secured rigidly to the lever 19 by means of the bolt 26, the 60 plate 22 with the plug 23, are moved downwardly, permitting the nurse to swing -the arm 42 so that the commode will be disposed under the commode opening.

The lower sheet for the bed is made in two sections, which overlap over the commode openin and these sheet sections are held stretche over the mattress by buttons on the mattress, which engage button-holes in the sheetsections.

Having thus described my invention, I claim as'new and desire to secure by Letters Patent:
